What is the range of the quadratic function?

1 answer:

4 0

For every polynomial function (such as quadratic functions for example), the domain is all real numbers. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k .

Answer:

Step-by-step explanation:

First step: Find the slope, Using the Formula y2 - y1 / x2 - x1 =

6-4=2 3-1=2 then u divde the y/x 2/2=1 So the slope is 1.

Step 2: Use the Slope- Intercept formula, Y=mx+b so 4 = 1(1)+b so 4 = 1 + b

Step 3: subtract 1 on both sides so 4-1=3 1-1=0 so 3 is the Y-Intercept.
